Wallets & accounts

BiuBiu Tools never asks for a seed phrase and never holds your keys. You connect a wallet only when a tool needs to sign, and you can disconnect at any time.

Three ways to connect

A passkey-backed smart account. Your signing key lives in your device’s secure hardware and you authorize with Face ID, Touch ID, or a security key. There’s no extension to install and no phrase to back up.

  • It’s a Safe smart account operated with ERC-4337 account abstraction.
  • The same address works across every supported network.
  • Recovery is your responsibility: sync your passkey via iCloud Keychain, Google Password Manager, or a hardware key.

2. Injected browser wallet

Any wallet that implements EIP-6963 discovery (browser extensions and in-app browsers). BiuBiu detects them automatically when you choose to connect one.

3. WalletPair (scan to pair)

Pair a compatible wallet by scanning a QR code, then verify the short code matches on both screens before continuing.

Why smart-contract wallets only

Every connected wallet must be a smart contract account — either a native smart account or a plain EOA upgraded via EIP-7702.

Disconnecting

Disconnecting removes the wallet from this session. For the built-in wallet, your passkey stays on your device — you can sign back in anytime. Nothing is deleted on-chain.
